Let's talk about the video.

Susan's already told us it was between 2 and 5 a.m.

And how does that jive with the time we believe the killings went down?

Based on the timeline that police have already created, Nancy, they say that they're talking about 2 a.m.

to 5 a.m.

as the time that this action took place inside the home.

And that timetable we're looking at for the guy walking in the alley is during that time period.

I'm curious about the neighborhood.

I don't see anybody else walking around between 2 and 5 a.m.

See the person walking?

It looks like people park their cars as you, like you pull in in front of the house.

See, on both sides of the street, I see cars parked in front of the homes, like where you put your trash out, right there on the street.

They look to be condos or two-, three-story narrow homes.

Why is he walking up and down in a residential area at 5 o'clock, 2 o'clock a.m.?

Susan, what can you tell me about the neighborhood?

It appears he knew this route, knew what to do and planned it, in my opinion.

You're seeing video of the home from our friends at WSYX ABC 6.

So this is a residential area.

Who is this guy walking up and down right near the home?

It's obviously caught on ring cam.
